PAUL BOGHENEK, 'OF NEW YORK, N. Y.

COMBINED CLAMP AND WRENCH.

Application filed April 22, 1918.

To all whom it may concern Be it known that I, PAUL BOOHENEK, a

' subject of the Emperor of Austria, and a resident of the city of NewYork, borough of Manhattan, in the county and State of New York, haveinvented a new and Improved- Combined Clamp and Wrench, of which thefollowing is afull, clear, and exact description.

V The object of the invention is to provide a new and improved combinedclamp and wrench arranged for convenient use as a hand clamp, benchclamp, monkey wrench, pipe wrench or like tool. is to permit the user toconveniently hold and manipulate the clamp and wrench. Another object isto construct the tool of comparatively few parts not liable to geteasily out of order.

With these and other objects in view, the invention consists of certainnovel features of construction, as hereinafter shown and described andthen specifically pointed out in the claim.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the tool arranged as a bench clamp,parts being shown in section;

Fig. 2 is a similar view of the same with parts in section and arrangedas a pipe wrench;

Fig. 3 is a sectional plan view of the same on the line 33 of Fig. 1;and

Fig. 4: is a side elevation of a modified form of the bench clamp andwrench.

The shank 10 of the combined clamp and wrench is provided at one endwith a fixed jaw 11, and along the inner edge of the shank 10 arearranged gripping teeth 13 adjacent the fixed jaw 11 and rack teeth 12extending from the end of the gripping teeth 13 to near the end of theshank, as plainly indicated in Figs. 1 and 2. On the shank 10 is mountedto slide lengthwise the bearing 14 of a movable jaw 15 adapted to 00-act with the fixed jaw 11. An operating screw 16 is journaled on themovable jaw 15 and engages the rack teeth 12 to permit of moving the jaw15 toward or from the fixed jaw 11 according to the direction in whichthe operating screw 16 is turned at the time by the user.

Specification of Letters Patent.

Another object 1 Patented Oct. 22, 1918.

Serial No. 230,110. 1

One of the jaws is provided with an adjustable cheek 20, for instance,as shown in Fig. 1, this cheek 20 is pivoted at 21 on the movable jaw15, while, as shown in Fig. 4:, the cheek 20 is pivoted at 21 011 thefixed jaw 11. The check 20 is provided with a socket 22 engaged by aball 23 formed on one end of a screw 24 screwing in the correspondingjaw 15 or 11, as indicated in Figs. 1 and 4C. The screw 24 is providedwith a suitable head 25 adapted to be taken hold of by the operator toscrew the screw forward or backward to swing the cheek 20 from itsnormal position as shown in Fig. 1, into an inclined position, as shownin Fig. 2, or back from the latter to the normal position. When thecheek 20v is in the normal position shown in Fig. 1 its face is parallelto the face of the jaw 11, and in this position the tool can be used asan ordinary hand clamp or a monkey wrench. When it is desired to use thetool as a pipe wrench then the cheek 20 is swung into inclined positionrelative to the other jaw to coact with such jaw and the gripping teeth13 with a view to securely grip a pipe or a similar round article, aswill be readily understood by reference to Fig. 2.

In order to prevent the ball 23 from becoming accidentally disconnectedfrom its socket 22, the cheek 20 is provided at opposite sides of thesocket 22 with cut-out portions 26 to provide thin walls, which areupset as indicated at 27 in Fig. 3, to engage the ball adjacent thescrew 24: to prevent the ball from accidentally leaving the socket 22.The face of the cheek 20 is preferably provided with a lengthwiseextending V- shaped groove 28 to permit of conveniently gripping small,round articles between the jaw 11 and the walls of the groove 28.

In order to permit convenient handling the tool or attaching it to abench, table or other support use is made of a convertible handle andattaching device 30 arranged as follows: The bearing 14 is provided atthe outer side with a boss 29 in which is secured a rod 31 provided atits outer end with a screw thread 32 and on which fits a sleeve 33having a bore 3 1 provided at one end with a screw thread 35 screwing onthe thread 32 of the rod 31. When the sleeve 33 is in position on therod 31, as shown in Fig. 2, then the rod and sleeve form a convenienthandle for the operator to take hold of while manipulating the tool. asan ordinary hand clamp with the cheek 20 in the position shown in Fig.1, and when using it as a pipe Wrench with the cheek 20 inclined asshown in Fig. 2. When it is desired to use the tool as a bench clampthen the sleeve 33 is unscrewed from the rod 31 and the washer 36 isremoved from the rod, and then the rod 31 is engaged with a hole 41formed in a bench, table or other support 40, as indicated in Fig. 1.The washer 36 is then rengaged with the rod 31 and the sleeve 33 is nowreversed and screwed on the threaded end 32 of the rod 31, and againstthe washer 36, to clamp the bearing 14 firmly on the top of the support40. The tool is now in position for use as a bench clamp or a vise, andon turning-the operating screw 16 the shank 10 with its movable jaw 11is moved lengthwise to clamp the desired article between the jaws. It isunderstood that after an article is placed between the jaw 11 and thecheck 20, the jaw 15 is moved up by turning the operating screw 16, andthen the cheek 20 may be inclined by adjusting the screw 24 to obtain afirm final clamping of the article between the jaw-11 and the cheek 20.The same action takes place when the cheek 20 is pivoted 0n the fixedjaw 11 instead of the movable jaw 15, that is, final clamping adjustmentis made by the operator turning the screw rod 24: to move the cheek 20into slightly inclined position.
